BACKGROUND OF THE INVENTION Field of the Invention

The invention relates to the field of fire and/or smoke protection, andrelates to a device to protect a person from smoke and/or fire.

Description of Related Art

In the event of a fire in a building, the fire must be prevented fromspreading and the persons in the building must be swiftly evacuated. Forthis purpose, various fire extinguishers and fire alarms are available.Smoke generated by a fire quickly spreads along the ceiling and canreach locations far away from the origin of the fire. On account of thisphenomenon even persons who have no need to hurry with evacuation becomealarmed and panic. To prevent such a panic, exposed anti-smoke screenshave been developed to be hung from the ceilings at intervals. Testsshow that these anti-smoke screens can effectively prevent the smokefrom spreading along the ceiling. The anti-smoke screens can be builtpenetrating the ceiling and installing the ceiling member is troublesomeand heavy. Anti-smoke screens are, for example, known from the followingapplications GB1579848 and FR2931177. Wherein GB1579848 discloses arodlike fastening in between a two plates screen and FR2931177 disclosesa vertical sealing between two adjacent glass plates.

The function of smoke barriers is to control the movement of fireeffluent within supporting constructions by forming a barrier. Thefunctions of active or manually deployed smoke barriers are identical tothose of static smoke barriers, but they also have the ability to beretracted and concealed when not in use.

Typical functions of smoke barriers are:

to create a smoke reservoir by containing and limiting the travel of thesmoke;

to channel smoke in a pre-determined direction; and/or

to prevent or retard smoke entry to another area or void.

SUMMARY OF THE INVENTION

It is therefore an object of the invention to provide an improved deviceto protect a person from smoke and/or fire and an improved a methodfixing a smoke barrier system to a supporting construction, which mayovercome the disadvantages of the prior art. Furthermore, the inventionmight enable a safe escape and/or a rescue of a person.

The smoke barrier system includes at least two brackets, namely a firstbracket and a second bracket, a glass panel and fastener means. Theglass panel includes at least two holes, respectively, openings. Thefastener means is equipped to fasten the bracket to the hole of theglass panel. In particular, the fastener means are equipped to fasten afirst bracket to a first hole of the glass panel and a second bracket toa second hole of the glass panel. The brackets are equipped to be fixedto a supporting construction on which the smoke barrier system isinstalled and/or is to be installed. The smoke barrier system furtherincludes at least two first washer, wherein the washer, in particularthe first washer, is arranged between the fastener means and the glasspanel. The washer is an intumescent washer. The intumescent washerexpands under thermal influence of a fire and/or hot gas, wherein thehot gas can be hot smoke. Under thermal influence, the washer can form athermally insulating layer. Furthermore, under thermal influence theintumescent washer can build up additional pressure between the fastenermeans and the panel.

This can enable to improve the secure fixation of the smoke barriersystem to the supporting construction. The intumescing washer canincrease the holding force between the fastener means and the bracketupon thermal influence of fire and/or hot gas as the addition pressure.

Additionally, the thermal insulation formed by the washer can preventand/or reduce the thermal load on the holes and/or the fastener means.The reduced thermal load can increase the stability respectivelyintegrity of the smoke barrier system in the event of a fire, hot smokeand/or the impact of hot gases. The integrity of the smoke barriersystem can be viewed as the ability of the smoke barrier system tomaintain its soundness for the purpose for which it is intended withoutthe transmission of significant quantities of flames, hot smoke and/orhot gas to the non-exposed side of the smoke barrier system.

In this text the smoke barrier system is a device to device to channel,contain and/or prevent the migration of smoke (fire effluent). The smokebarrier system can also be called Smoke Curtains, Smoke Blinds and/orSmoke Screens. The smoke barrier system can build a smoke reservoir. Thesmoke reservoir is a region within the supporting construction limitedor bordered by the smoke barrier system and/or structural elements ofthe supporting construction so has to retain a thermally buoyant smokelayer in the event of a fire.

The intumescent washer expands upon exposure to a fire, hot smoke and/orhot gases. Due to the expansion, the washer has a lower density afterswelling as compared to the non-swollen washer. The expansion can bedirected in any direction, meaning it can be an isotropic expansion oran anisotropic expansion.

The glass panel includes two substantially parallel major surfaces areasThe major surface areas may also be called flat sides. The edges of thetwo flat sides are connected to each other via an end side. The end sidehas a smaller surface area than the flat sides, and a dimension of theend side corresponds to the thickness of the glass panel. In this textthe term ‘end face’ is used for the circumferential area between the twoflat sides, which is also called “edge” or “narrow side” of a glasspanel, or a surface thereof. An edge region of the glass panel, whichmay be arranged close, respectively, closest to the supportingconstruction, can be also referred to as a fixation region. The edgeregion extends not only via the end face of the glass panel but alsospreads over a region of the flat side adjacent to the end side.

The term temperature influence, respectively, thermal influence, meansthat the temperature of the air, respectively, gas, is at least 80° C.or higher. Normal room temperature and slightly elevated summertemperature of approximately 40° C. is not considered as temperatureinfluence.

The holes can be arranged in the edge region of the glass panel. Thiscan enable a stable connection between the bracket and the glass panelas the bracket can have a minimised dimension extending between thesupporting construction and the glass panel. The holes can reach fromone flat side of the glass panel to the opposite flat side of the glasspanel. The holes can be arranged essentially at a right angle withrespect to the flat side of the glass panel.

The washer can be arranged around the holes. This allows for asimplified arrangement of the washer between the fastener means and theglass panel.

The washer can be a flat ring or perforated piece of solid material. Theflat perforated solid piece can have an arbitrary shape, for example arectangular, hexagonal or a triangular shape. The washer can preventleakage and or distribute pressure acting on the glass panel. Theperforation of the washer can be aligned with the holes of the glasspanel. The washer in the context of this text can also include severalpieces that are separately or together arranged between the fastenermeans and the glass panel. For example, the washer can include severalpiece, wherein said pieces have approximately similar thickness. Thepieces can be arranged around the holes such that the pieces are inadjacent contact with each other. It might also be the case that thepieces are not in contact with each other. The pieces can also cover atleast two opposite sides of the holes, wherein the opposite sides can bearranged on the same flat side of the glass panel.

The fastener means can clamp the glass panel to the bracket. Forexample, in case the fastener means is designed as bolt and the washeris arranged under the head of the nut or bolt clamping the glass panelto the bracket.

The outer diameter of the washer can be larger than the outer diameterof the holes. This can enable a pressure distribution on the glass panelsurrounding the holes originating from the fastener means and/or thebracket. Furthermore, the washer can protect the holes in case of attackof thermal influence, as the washer can cover the holes and prevent apassing of the heat and/or smoke through the holes.

The supporting construction can be a connection to the roof,respectively, the ceiling. The smoke barrier system can be fixeddirectly to the ceiling respectively roof, wherein the supportingconstruction can be view as ceiling respectively roof.

As explained above: The smoke barrier system can include at least twobrackets. The glass panel can include at least two holes. The fastenermeans can be designed to fasten a first bracket to a first hole of theglass panel and a second bracket can be fastened a second hole, and soon. This enables precise and stable fastening of the glass panelrelative to the supporting construction.

The brackets can be essentially identical. The size and/or positioningof the holes can correspond to each other. It is also possible that thepositioning and/or size of the holes can determine orientationalalignment of the glass panel in the supporting construction.

The smoke barrier system can include at least two first washers that arearranged close to the first bracket and respectively the second bracketbetween the fastener means and the glass panel. Additionally the smokebarrier system can include at least two second washers. The secondwashers are arrange opposite to the first washers, as explained above.

The washer can be arranged on the flat side of the glass panelrespectively of the smoke barrier system facing the temperatureinfluence. As already mentioned above, the temperature influence canoriginate fire and/or hot gas. In other words: the washer can bearranged such that it is facing the temperature influence.

The smoke barrier system can further including a second washer. Thesecond washer can be arranged between the fastener means and the glasspanel. The second washer can be arranged vis-à-vis of the first washer.The second washer can as well as the first washer be an intumescentwasher. This can enable an improvement of the stability of the smokebarrier system independent of the side from which the temperatureinfluence occurs, as both sides of the holes can are covered by theintumescent washer. The two washers can be essentially identical.

The smoke barrier system can include a grommet, wherein the grommet isarrangeable in the holes. The grommet can enable a sealing of the holes.Furthermore, it might be possible that the grommet is designed a guidingsleeve for guiding the fastener means through the holes. Additionally,the grommet can enable an isolation of the fastener means from the innercross section of the holes. The grommet can prevent, respectively,minimise the direct contact between the fastener means and the glasspanel. The isolation can be beneficial in case of temperature influenceat the inner cross section of the holes can be enabled by the grommet.This means that in case of temperature influence the fastener means canstart to heat up and the grommet can reduce the heat transferred to theglass panel. The reduced temperature load on the glass panel can enablethe smoke barrier system to resist the temperature influence for alonger period of time than without such an isolation. Furthermore, theload of the fastener means can be distributed by the grommet. The innercross section of the grommet can at least partially correspond to theouter cross section of the fastener means. The outer diameter of thegrommet can essentially correspond to the inner cross section of theholes.

The smoke barrier system can be a static smoke barrier system. A staticsmoke barrier system does not require additional power supply and isconstantly operational. The static smoke barrier is permanently fixed inits fire operational position.

In general, smoke barriers can be categorised in the followingcategories: static smoke barrier with flexible material or rigidmaterial and active smoke barrier with flexible material or rigidmaterial. Static smoke barriers can be fixed in their fire operationalposition at all times and according to their design classification (moredetails see below). Static smoke barriers systems can be used asalternatives and/or additional to the elements of the supportingconstruction which could act as permanent static smoke barriers.

The glass panel can be a transparent and/or translucent glass panel.This enables a free and open view throughout the supportingconstruction. The view is not be blocked by an opaque glass panel.Nevertheless, ornaments and decorative and/or coloured prints can bearranged on the glass panel and shall not be excluded. Due to thetransparent respectively translucent properties of the glass panel thewhole supporting construction can occur more open and feel larger thanwith an opaque, non-transparent glass panel.

The glass panel can be a monolithic glass panel. Such a monolithic glasspanel can enable a simplified fixation of the smoke barrier system tothe supporting construction, as a monolithic glass panel is lighter thana composite glass panel including at least two glass panel elements.

The glass panel can include glass. The glass panel, in particular theflat glass panel, in most cases can be considered as transparent glasspanel. The glass panel can also be a ceramic glass, in particular avitroceramic. The glass panel can be special bent glass panel. Thermallyor possibly chemically prestressed glass can be particularly favourable.A transparent glass panel can be based on polymer (e.g., frompolycarbonates or polymethyl methacrylate (PMMA; acrylic glass),partially crystalline glass (ceramic glass) or composite systems withglass elements and plastic carriers, are also considered as alternativesto glass based on silicon oxide. The glass panel can also include glasson a borosilicate basis. In other words: The glass panel, in particulara transparent and/or translucent glass panel, can include a siliconbased glass, a borosilicate, vitroceramic, a polymer based panel and/orother types of glass.

The glass panel can include fire resistant respectively temperatureresistant properties. The glass panel can be a fire-resistant glazing.The term “fire-resistant glazing” has a functional meaning and is not tobe understood as being limited to certain materials (specifically: glassin the narrow context), but expressly also includes constructions withtransparent or translucent glass panels of the above mentioned and othermaterials.

The glass panel can be the temperature resistant glass panel. The smokebarrier system can be classified at least as a DH or D₆₀₀ smoke barrieraccording to EN 12101-1:2005+A1:2006. In other words: The smoke barriersystem can be a fire-rated smoke barrier system. The fire-rated smokebarrier system is characterized by a fire resistance durationrespectively fire resistant rating. EN 12101-1:2005+A1:2006 establisheda standard for testing smoke barriers.

The temperature resistance or fire resistance can be considered as theability of a smoke barrier system to form an effective barrier againstthe spread of flames, smoke and/or hot gas. A temperature resistance canbe defined as the minimum number of minutes during which the smokebarrier system in the examination meets the criteria of the standardizedexamination procedure with defined boundary conditions (EN12101-1:2005+A1:2006). Accordingly, the temperature resistance can bedetermined under a certain temperature stress. EN 12101-1:2005+A1:2006requires an exposure of the smoke barrier system to a heat respectivelytemperature influence of 600° C. for the classification as a D₆₀₀ smokebarrier system. Higher temperature according to a standard heat curve(EN 1363-1:2012) are required for classification as DH smoke barriersystem. Furthermore, it is required that the DH and D₆₀₀ smoke barriersystem do not release flaming droplets or particles within the first tenminutes of the standard test. The period within which the tested smokebarrier system meets requirements of EN 12101-1:2005+A1:2006, permitsthe timely classification of the smoke barrier system. In other words:The classification of the smoke barrier system is a temperature-timeclassification. The standard classification is a D₆₀₀-class according towhich the smoke barrier is exposed to a heat of 600° C. An advancedsmoke barrier system of the DH-class is exposed to a standard heatcurve. Furthermore, according to both classifications the smoke barriersystem does not release flaming droplets or particles in the first tenminutes of the classification test.

Classification periods are indicated for each classification in minutes,wherein the classifying times: 30, 60, 90, 120, or longer are to beused. The temperature resistance period respectively fire resistanceperiod is thus defined by at least 30 minutes. In general, a temperatureresistant smoke barrier system thus fulfils at least 30 minutes theappropriate criteria or requirements for temperature resistance. Theminimum criterion is the physical barrier. A temperature smoke barriersystem must therefore be classified at least as D₆₀₀ 30. Fire ratedsmoke barrier systems have to withstand the temperature of the standardheat curve and are classified as at least DH 30 smoke barrier system iffulfilling the corresponding requirements for at least 30 minutes.Accordingly, the fire rated smoke barrier system must therefore beclassified at least as DH 30.

The smoke barrier system can be a fire-rated smoke barrier systemaccording to the DH and/or D₆₀₀ classification.

The bracket can be designed for a point fixation of the glass panel.This enables for the precise positioning on the glass panel. The bracketcan fix the glass panel at a single point. In contrast to that rigidbracket does not fix the glass panel at several positions. Such amultiple fixation with one and/or multiple bracket would result in thenecessity to provide a very precise conformity of fixing positions ofthe bracket and the glass panel. In the single fixation per bracket acertain margin is possible for precise fixation of the glass panelrelative to the supporting construction.

The bracket can be designed as a retaining bar. The retaining bar canextent along the edge region of the glass panel. In such an embodimentthe retaining bar can be viewed as fastener means and the glass panel.The intumescent washer can have a strip like shape and is arrangedbetween the bar clamping the glass panel and the glass panel.

The smoke barrier system can include at least two panels. Each glasspanel can be fixed to the supporting construction by a bracket and theglass panels are arranged adjacent to each other. The adjacent panelsbuild a uniform smoke barrier system. The space between the adjacentpanels is minimized to allow minor thermal expansion of the glass panelsdue to a temperature influence and to prevent the passage of fire, hotsmoke and/or hot gas.

The method for fixing a smoke barrier system to a supportingconstruction includes the steps of:

providing a brackets designed to be fixed to a supporting constructionon which the smoke barrier system is to be installed,

The grommet can include a temperature sensitive material. Thetemperature sensitive material can melt upon temperature influence. Thetemperature sensitive material can melt at a temperature of 200° C.-300°C. The temperature sensitive material can include a chlorophrene and/ora derivate thereof.

The glass panel can include at least two holes, a corresponding amountof brackets and grommets can be provided, wherein in each hole a grommetis inserted. Each bracket can be fastened to one corresponding hole ofthe glass panel.

An additional, second intumescent washer can be provided, theadditional, second washer can be arranged on the opposite side of thehole opposite to the first washer. The fastener means can be insertedinto the hole passing both washers arranged on opposing sides of theglass panel.

The fastener means can include a bolt, a nut and/or a clamping plate.

As already mentioned above, the intumescent washer can prevent and/orreduce the thermal load on the hole and/or the fastener means. In casethe grommet is inserted in the hole, also the grommet is protected fromthermal influence of a fire and/or hot smoke as the intumescent washercan build an insulation layer protecting the grommet inside the hole.This can also prevent a self-ignition of the grommet during the thermalinfluence respectively fire test.

Additionally, the intumescent washer can be used for cold fitting uponinstallation of the smoke barrier system at the supporting construction.The cold fitting includes the fastening of the glass panel to thebracket. The cold fitting enables the positioning of the glass panel assmoke barrier system in the cold state without being thermallyinfluenced. Cold fitting can be crucial for the installation of thesmoke barrier system.
